  • 잎도열병의 발생은 잎도열병병반수조사 4일전까지의 2개반순의 분생포자비산수와 고도의 정의 상관이 있었고 이삭도열병발생은 진흥품종에서 출수기 분생포자비산수와 정의 상관관계였다. 수잉기에 있어서 잎도열병의 병엽수와 이삭도열병발생은 고도의 정의 상관, 지엽의 규화도와는 부의 상관이 있었다. I-KI법은 30분이내에 도열병균 침입에 의한 감염부위를 알 수 있어 잎도열병의 초발은 4일전에 예찰이 가능하였으며 I-KI법과 잎도열병발생과의 양적인 관계를 구명하는 것도 가능한 것으로 나타났다.

  • Purpose: This study was conducted to explore clinical practice performance according to type of practice in students in pediatric nursing and the relationship with satisfaction of clinical practice. Methods: The subjects consisted of 531 nursing students (307 at a pediatric ward and 224 at a nursery) from 5 colleges of nursing. Data collected from March to June 2012 were analyzed using descriptive statistics, t-test, AVONA and Pearson correlation coefficients. Results: Clinical practice performance on direct nursing activity was significantly different according to the course on pediatric nursing, grade point average, and satisfaction of nursing major. Observation practice was different according to type of college, the course on pediatric nursing, grade point average, duration of practice and clinical educator in the pediatric ward. In the nursery, direct nursing activity was significantly different according to the type of college, the course on pediatric nursing, hospital type, and duration of practice. Observation practice was different according to type of college, satisfaction of a nursing major, and the clinical educator. In addition, significant correlations were found between clinical practice performance and satisfaction of clinical practice. Conclusion: Our research can assist effective pediatric nursing practice planning for nursing students.

  • Plastics are one of difficult materials for recycling due to their characteristics in use. Recycling ratio of waste plastics was around 40% in last year in Japan, which includes energy recovery. Feed stock recycling and mechanical recycling are not easy because of additives in commercial plastics. Then, pyrolysis treatments have been done to recovery energy. Although plastics are easy to fire, complete combustion of them is not easy if anti-firing agents are added especially. Therefore, researches on pyrolysis or combustion behaviors of plastics containing additives are important from a view point recycling of plastics. Direct observation of popular plastics like polystyrene (PS), polycarbonate (PC), polyphenyle ether (PPE) and polyvinyl chloride (PVC) to investigate their pyrolysis behaviors in the present study. In case of PS, melting and gas evolution started at 9$0^{\circ}C$ and 39$0^{\circ}C$ respectively. And combustion finished at 445$^{\circ}C$. On the other hand, more than $600^{\circ}C$ and sufficient oxygen are required for complete combustion of PC and PPE.
